Learn about a novel approach to building large-scale fault-tolerant quantum computers through this conference talk that introduces extractors as a new primitive for quantum low-density parity-check (QLDPC) codes. Discover how extractors can transform any QLDPC memory into a computational block, enabling fault-tolerant measurement of logical Pauli operators in O(d) physical syndrome extraction cycles without requiring qubit connectivity rearrangement. Explore the proposed extractor architecture, which features fixed-connectivity LDPC design connecting multiple extractor-augmented computational blocks with bridge systems to implement universal quantum circuits through parallel logical measurements. Examine how this architecture compiles away single-block Clifford gates when combined with high-fidelity |T⟩ states, and understand the scalability implications with extractor sizes of Õ(n) for n-qubit codes, offering significant potential for practical optimizations in quantum computing implementations.
